' Specification of Letters Patent.

Patented Mar. 18, 1319.

Application filed June 2, 1916. Serial No. 101,327.

the form will hold its contour and shape and become capable of resistingoutside strains and pressure and not'yield readily to jars and suddenimpact; retaining at all times a degree of rigidity requisite for theuse it is intended to fulfil.

In order to produce such a form I use a large heated female forming rollwith its entire periphery formed of depressions for receiving the formand a multiplicity of small heated male forming rolls disposed aroundthe female forming roll each having a continuous formation of maleformers which fit the female roll depressions, in this way a continuouspressing, embossing, ironing and calendering is provided and when theform passes through these rolls it is of the required degree of rigidityand firmnem and has an ideal body.

In the drawings:

Figure 1, is a side elevation of the machine, showin the drivingmechanism,

Fig. 2, is a cut elevation of the back end of the machine,

Fig. 3, is a section of the machine, partly in elevation, it being takenat the opposite side of the view shown in Fig. 1,

Fig. 4, is a section on line 4--4 of Fig. 1, and

Fig. 5, is a side view of the machine which forms a continuous sheetwhich is operated upon after it passes through the forming rolls andproduces a form varying somewhat in contour, and being known ascorrugated paper.

This invention relates articularly. to the feed-in ironing,'calender1ngand embossin rolls o the machine. The strip of m'ateri which is to' beacted upon by the present invention may be prepared by any suitablemechanism WhlCh will bring it into a condi.

tion ready to be acted upon by the forming rolls.

The frame or base of the machine is marked 1 and is of any preferredform. In order to carry out my construction, I provide housings 2 inwhich I journal two feed rollers 3 and 4, carrying at one side the gears5 and 6. I also provide alarge hous ing 7 in which I journal the largefemale forming roll 8, provided with continuous peripheral depressionsor female dies 9; this roll 8 is hollow to enable it to be heated, andona hub 10 of roll 8, I fasten a gear 12.

I surround this large roll 8 with a multiplicity of smaller male rolls13, all of the same form ation. each carryin-gthe male formers or dies14, each, in the present instance, having eight of such formers, inFigs. 1, 2, 3 and 4, but in Fig. 5 carrying a. greater number thereof.

Each of these male .forming rolls 13 is journaled in the housing 7 andat one side each carries a hub 15,0n which is placed a gear 16. Thesesmall or male rolls 13 are each hollow in order that they may .be

heated. I show one form of heating means, which I attach to the machinein any desired manner, and shown in Fig. 4 particularly. To providethese heatin means, I provide a main gas intake pipe 1 provided withshortpipes and valves 18, which carry the gas to the burners 19whic'hextend with all the rolls, and when lighted heat all saidrolls tothe required intensity.

On the insideof the machine and extending arms of the same, is an apron20 supported 'on pins or the like 21. I do not need this construction,however, in Fig. 5.

I further provide a housing 22, on which I support or journal a roller23 and a female roller 24, having the depressions 25 into which thefinished form fits. On this roller 24, .at two of its edges where two ofsprocket 32, the sprocket chain 33 passing over and engaging saidsprockets.

.105 sprocket 31 and on the roll 24, I place a.

In order to thread the machine, ll provide, on one of the rolls 13, astud shaft 3% carry= ing an eccentric bush 35 which carries anextendingarin38, on which arm is a bar 377,

said bar extending across the machine. The

strip of material is marked 38 and is fed into the rollsof the machinethrough rollers 3 and 4:, making a loop 39, which loop always providesthe required amount of material for the forming rolls, so that it will Inot come from the feeding rolls; when the strip of material reaches thefirst male roll 13, said roll is lifted through the agency of theeccentric bush 35 and its connection being lifted, raising the roll 13and when thus lifted or elevated the material 38 is slipped intoposition between said first roller 13 and the large roll 8; theeccentric bush and connections then are brought into normal position,thus lowering the roll 13, the strip of material 38 is gripped andpasses onward between the forming rolls. The strip 38 is fol and feedsitself around through and berevolves the gear 12 on said roll, whichgear meshes with each of the gears 16 on the male forming rolls l3 andthus all said rolls 13 are forced to revolve or rotate, the formers 1 1on said rolls fitting into the depressions 9 in roll 8 and thus the formis shaped between said rolls. The revolution of the large forming roll 8also revolves the sprocket wheel 31 over which the sprocket chain orhelt33 operates, and said helt also pam'ng over and engaging thesprocket wheel 32 on roll 24 revolves said roll 24 and forces the gear28 to mesh with the gear on roller 23, and thus motion is imparted tosaid rollers 23 and 2d, forcing them to revolve. The feed rolls 3 and lcarrying the gears 5 and 6 may be operated in any desired manner, butare generally operated by the mechamsm which operated the completemachine, no mechanism being shown in the drawing for operating them, asit is not essential to the disclosure of my invention.

In Fig. 5 I show the rolls forming the sheet into a somewhat difierentcontour, and do not show any mechanism for severing the sheet butillustrate a pastin apparatus for facing the finished strip or s eetwhen it comes from the formin roll. 1 will describe thisparticular-device in detail.

0n base 1, in Fig. 5, ll provide a housing 40 in which I journal the twosets of paste rollers ll and c2, revolving shown by arrows. These setsof rollers receive the aste from the paste troughs l3 and 44-, t roughthe agency of paste rollers 45 and 4&6.

At front of machine I provide a roll of paper t? which is to hecorrugated, supported in. a frame e8 upon which it revolves. in brackets49 ll revolubly support paper rolls 50 and 51.

The paper to he corrugated passes through the forming rolls 8 and 13,and is marked 38, when it has passed through said rolls,

it is corrugated in contour and the product here is marked. 52. Thepaper 53 and 54 ed of the rolls 50 and 51 passes over the rolls 55 and56, and as it thus passes over .said rolls comes in contact with thepaste rolls ll and 42, they receiving the paste, the rolls 55 and 56pressing it onto said corrugated paper sheet 52; the finished productbeing marked 57. c

The rolls 8 and 13 for making the formation, as shown in Fig. 5, havethe formers and depressions on their face or periphery of a difierentcontour than those shown in the other figures.

The large female forming roll operates in one direction and the smallmale forming rolls operate in an opposite direction.

Paper can be formed up under these heated forming rolls very rapidly andat the same time the productis of a high class as it is perfectly formedand has a solid and smooth surface and has a texture highly eiiicientfor use in forming articles for which the same is intended in acommercial way.

It will be understood that I can make the formers and depressions of thevarious rolls of any desired configuration, so that paper forms otherthan the ones specifically herein referred to, maybe produced by myinvention.

From the above description it will he seen that the improved machine formaking paper forms constructed according to my invention is or aninexpensive and extremely simple nature and is especially well adaptedfor the purpose for which it is designed, and it will also be obviousfrom the above description that the machine is capable of considerablemodification without material departure from the principle and spirit ofthe invention, and. for this reason ll do not wish to be understood aslimiting myself to the precise form and arrangement of the several partsoi the machine as herein set forth in carrying out my invention inpractice.

What I claimas new and my invention and desire to secure by LettersPatent is:

1. in a machine for makin paper forms, a rotary forming roll, provi edwith continuous depressions, a series of forming rolls each providedwith a continous set of rormere on their periphery, the formers on thelatter rolls fittin into'the depressions of the formin rol and of saidseries of forming r01 s provided with means for raisin and lowering thesame in order to thread said rolls with the material, and means forrevolving all said rolls.

2. In a machine for making paper forms, a large, single, heated femaleforming roll and a series of male heated forming-rolls 10 surroundingsaid female forming roll at its and means for rotatmg all said rolls.
